Scott Joplin plays Scott Joplin (New Rag & Fig Leaf Rag)

In 1916, Scott Joplin made a batch of Piano Rolls for Connorized, these being the only recordings of Scott Joplin playing the piano in existence. The rolls themselves are extremely rare (and were reportedly heavily edited by the company before release) but in the 1950s, some of the rolls were recorded onto 78. These aren't exactly easy to find either, but do come up occasionally.
